LAMP-BURNER.,

SPECIFICATION forming partof Letters Patent No.V 282,958, dated August 14, 1883.

` Application filed March 17, i883. (No model.)

will enableothers skilled in the art to which it.'

pertains to make and use it, reference being had to the accompanying drawing, which .forms part of this speciication.

` My invention relates to an improvement in lamp-burners; and it consists in the, combina- `tion of a double-wick tube, a spring for mov ingthe wick, and a mechanism for contracting and expanding the spring, whereby` the wick is raised or lowered according as more heat or light may be desired, as will be more fully described hereinafter.

The object of my invention is to provide a tubular burner for lamps, stoves, or other uses, and to furnish itwith means for evenly raising and lowering the wick. i

The accompanying drawing represents a vertical section of my invention.

'A represents the vouter and B the inner wicktube, between which tubes the wick C is placed. This wick is connectedby means of a wire or `any other suitable appliances at its lower end to a ring, H, which moves vertically between thetwo tubes.. Attached to the under side of this lring H is asuitable spiral spring, E, which spring, as it expands or contracts, moves the ring H with it.

At a suitable point between opening or hole, up through which passes the` wire or cord D. The upper end of `this cord is attached to the under sideof the ring H, so that when the spool G isturned in one direction the cord will be wound upon the spool and the ring VH drawn downward. `As soon `as the spool G is relaxed in the vslightest the expansion of the spring forces the ring H upward, and with the ring the wick. This spool may extend entirely across through the center of the burner and have a second cord attached to its Opposite end, which cord will also extend up through the support S and be fastened to the under side of the ring H.

\ Rising above the top edgesof the two wiektubes will be placed a suitable spreading device, I, for the purpose of spreading the iiame Outward, and thus `increasing the light and heat. I

The great advantageof my invention consists in raising and lowering the wick evenly at all points, so that the wick never moves more upon One side than the other.

Having thus described my invention, I claim l In an Argand lamp-burner, the combination WILLIAM P. OAsrnnsON.
